This study was conducted to see the application effect of learning by ability in Mat exercise. 367 Male middle school students who were second grade were served as subjects. They were divided into control group and experimental group. Control group was hetrogeneous group and experimental group was organized group by ability. After 8 hours' learning of Mat exercise, their motor performance were compared. The following conclusions were obtained; 1. In teaching of Mat exercise in Male middle school, group-organization by ability was more effective than hetrogeneous group-organization. 2. In stepped and systematic teaching materials such as Mat exorcise , effective motor skill improvement is possible through leaching method of group - organization by ability. 3. Especially in the learning of difficult motor events and motor events which need repeated practice and which lack of pre-learning, application effect of learning by ability is big.

In this paper, the scattered electric fields is computed to predict the shielding zone by analysing the effect of the reflected azimuth anlge at the building, and considering the path differences at observation point between the rays from origin and any point in the building. The scattering coefficients. which are applicable to the prediction of shielding zone. are computed and compared with measured one. We found that the scattering power become weak over 10 degree of the azimuth angle at which the scattering coefficient is lower than 40 dB. From this, the shielding zone can be estimated.

The goal of this paper is to predict the range of the reflection coefficient on the area which is divided by the satellite photograph in Cheju. We select the sample points on the smooth surface and measure the field strength. The range of the reflection coefficients on the sample area are obtained by the regression analysis as function of the coefficient for incidence angle and the measured field strength. The field strength in the divided area are obtained using this coefficient. The difference between the measured results and theoretical predictions is only within 5dB.

In order to minimize the loss of wireless data, an indoor radio environment is analyzed. As received signal is composed of multipath wave being caused by various media. the factors of signal fluctuation are studied by using the electrical characteristics of media. An equation which is a function of the electrical characteristics is derived by using the polarizations of antenna and the reflection theory. We take the strength of waves in corridor and between the two floors. and compare the measured data with the theoretical data.

In the mobile radio communication system, we must study wave propagation characteristics for microcell and picocell environments because the conventional cellular environment is changing to microcell and picocell. In this paper, sample areas are selected to study propagation in variety of environment including the width of road, the built-up density and the height of building at Cheju city area. Sample area is separated two zones by break point at which the slope of the signal strength is changed. The location of the break point is calculated on first Fresnel zone clearance for antenna height variation. The slope and the standard deviation of the signal strength is obtained by the regression analysis. The break point distance can be used to define the size of microcell and to design of microcellular system.

제품디자인에 있어서 인간공학 적용과정에 관한 연구 : Hand-Drill의 손잡이 형태에 빠른 EMG 적용을 중심으로 Focus on EMG Application for the shape of Hand-Drill Grip

홍성수,한정완 한국디자인과학학회 1998 디자인과학연구 Vol.1 No.-

디자인에서의 인간공학의 활용은 그동안 대단히 무질서하고, 난잡하게 적용되었다. 이것은 아직까지 디자인이 미술적 재능이나 경험적, 감각적인 재능의 부산물로 인식되기 때문에 이 시점에서 디자이너는 인간공학 도입의 본래의 취지에 맞게 디자인을 객관적, 정량적인 방법으로 수행해야 할 것이다. 따라서 본 연구는 EMG 시스템을 이용하여 Hand-Drill의 손잡형태가 팔근육에 미치는 영향에 대한 가설을 통하며 Hand-Drill디자인시 보다 객관적인 인간공학적 접근방법을 모색하고 적정각도 및 굵기를 정량적으로 제시하고자 한다. 이를 위해 5명의 신체 건강한 20대 피실험자을 대상으로 Hand-Drill 손잡이 각도 굵기를 독립변수, 팔근육에 미치는 힘을 종속변수로 설정하여 Hand-Drill의 각도와 굵기가 팔근육에 미치는 영향에 대해 조사 분석하였다. 측정된 자료를 통계분석한 결과 각도 0°, 굵기 2.56cm일 때 근육에 미치는 힘이 적게 나타났다. 본 연구의 결과는 제품디자인에 있어서 EMG 신호를 이용하여 각 형태를 인간공학적 방법으로 정량화 하였고, Hand-Drill 디자인에 있어 각도와 굵기에 대한 추천지로 제안 될 수 있다고 본다. 추후에는 진동, 단면적 형태, 무게 등의 독립변수 요인을 추가 확대하여 Hand-Drill 디자인에 응용한다면 더욱 유용하리라 생각된다. Human Factor, a practical science that is an application fields, has been employed and used in industrial importance. But we limited Human Factor on anthrome design work, and have used it as sensible data only. It is necessary that scientific, quantitized and responsib be applied in industrial design. In this paper, I propos design process can be used in EMG system of biom Human Factor with responsible and quantitized characteristics of EMG system is described and the cap application of EMG system of industrial design is pre-experiment. I applied this result to joystick leve hydraulic excavator. In this paper, 1 emphasize that objective aid standa applied to EMG system experiment process and indu process integratively. And I suggest that systematic method be applied to H in industrial design.

연구목적 : 전산화 Standard Progressive Matrices(SPM) 검사의 한국인 성인 표준자료를 확립함으로써, 간이로 지능을 평가하는 경우에도 보다 정확하게 지능지수를 추정하기 위해서 본 연구를 수행하였다. 방 법 : 18세 이상의 남녀 정상인 자원자 353명을 대상으로 전산화 SPM 검사를 시행하고, 백분율 및 표준점수(T-점수)를 기준으로 하여 표준화 자료를 작성하였다. 전체 대상군을 성별, 연령별로 구분한 후 평균과·분포가 유사한 집단은 군을 합치는 방법을 사용하였다. 한국인 표준자료에 근거하여 추정한 SPM 지능지수와 외국인 표준자료에 근거하여 추정한 SPM 지능지수를 각각 KWAIS 지능지수와 비교함으로써 타당도를 검증하였다. 결 과 : 18∼30세, 31∼40세, 41∼50세, 51세 이상의 연령군으로 구분된 한국 정상 성인의 SPM 표준화 자료를 산출하였다. 본 연구 결과에 의한 표준화 자료를 적용하여 지능지수를 추정하는 것이 현재 사용하고 있는 외국인의 표준화 자료를 이용하는 것보다 KWAIS 지능지수에 더욱 근접한 결과를 보였다. 결 론 : 18세에서 50세까지의 한국인 남녀에게는 간이지능평가도구로서 전산화 SPM 검사의 한국인 표준화 자료를 유용하고 타당하게 적용할 수 있음을 확인하였다. Objectives : We conducted this study to provide standardized data of the computerized Standard Progressive Matrices(SPM) test in Korean adults. Methods : The computerized SPM test was administered to 353 healthy volunteers aged 18 years over. We provided the standardized data(percentile and standardized T-scores) for the groups with similar mean and distribution of SPM scores, which was originally divided by age and sex. The validity of the new standardized data was tested by comparing IQs estimated by SPM and K-WAIS. Results : The standardized SPM data were provided for four age groups : 18 to 30 years, 31 to 40 years, 41 to 50 years, 51 years and over. IQ estimated by this standardized data tends to be closer to IQ by K-WAIS than the IQ estimated by foreign normative data. Conclusion : The standardized data of the computerized SPM were proven to be a useful and valid tool for measuring IQ briefly, compared with the conventional way of measuring IQ.

Among all study students, 89% of students thought that Ki therapy was useful and wanted to have Ki therapy in case of medical attention, whereas only 11 % of students did not want Ki therapy. 6. Among study students with positive thinking about Ki therapy, 24% and 23% of students thought Ki therapy useful for (endocrine and skin diseases) and chronic adult diseases such as hypertension, cardiac disease, diabetes and obesity, respectively, whereas 21% and 18% of study students thought Ki therapy useful for neuropsychiatric disease and digestive diseases, respectively. 7. Regarding to the reason of attraction of Ki therapy compared with other treatment methods, 51% of students answered that Ki therapy gave comfortable and easiness to mind and 42% of students answered that it did not need any kind of injection or medicine.
